If you have already worked on a website development project, you have surely already met language Javascript. Indeed, it has long been the web language of the most popular scripts. Besides, to help you in your projects in JavaScript, you can call on a JavaScript developer Freelance on Coder.com!
Typescript, on the other hand, is a programming language more suited to large applications. Open Source, it was developed by Microsoft in 2012, mainly because the JavaScript code became too complex to manage when it was large -scale applications.
Before exposing the differences between the two, let's understand what of these two languages looks like!
Javascript
Often abbreviated JS, JavaScript is a web language which follows the ECMAScript provision. The compilation of JavaScript is done immediately before execution. It contains a dynamic typing, a syntax to hugs, first -class functions and an object orientation based on prototypes. With CSS and HTML languages, JavaScript is one of the essential technologies of the web.
What is Javascript for?
Javascript allows Create interactive web pageswhich constitute an essential aspect of modern websites. Since the vast majority of websites use it for the behavior of their pages on the customer side, it is logical that all web browsers have a JavaScript engine dedicated for this purpose. Note that if JavaScript engines were once present only in web browsers, they are now inserted in certain servers (generally via Node.js).
There are many JavaScript derivatives such as types Script, Coffeescript, Dart and Kotlin. These are also located in multiple applications formed with frameworks such as Cordova and Electron.
Inasmuch as programming language Multiparadigm, JavaScript supports imperative, events and functional styles and has an application programming interface (API) allowing it to process dates, text, standard data structures, Object Model (DOM) document without forgetting regular expressions.
Benefits of JavaScript
JavaScript may not be the most complete coding language, but it is used with HTML to improve the quality of web pages. In addition, there are thousands of experienced developers who code in JavaScript And this programming language is adopted by all browsers.
JavaScript can be considered the perfect solution for Small web projects And the small teams. It is common to use JavaScript without the help of construction tools, and if you use the use of frameworks, some of them do not support Typecript.
In addition, using libraries and existing JavaScript frameworks, you can Develop web applications faster while rationalizing your software development process.
Typescript needs to install the JS libraries you want to use: An additional definition type translated as an additional EPM package. It is therefore preferable to use a popular JavaScript library for your development, because it will be properly maintained in the future.
Typescript
Typescript is a programming language Object oriented and open source. Created and maintained by Microsoft, Typescript is actually a syntactic oversemble of JavaScript, adding an optional static typing to the passage.
What are the specifics of Typecript?
Typescript is a JavaScript outcry: in general, all that is the code in JavaScript is therefore also valid in typescript. So, if you save your JavaScript file (.JS) with a standard typecript extension (.TS), it will still work perfectly.
Typescript is intended for Construction of large applications and transomplile to JavaScript. Current JavaScript programs are also valid standard programs, and the language can be used to create JavaScript applications for server on the server side and not only on the customer side.
There are many alternatives for transcompilation To transform Typescript into JavaScript. In particular, the TypeScript verifier, by default, can be used, or the Babel compiler.
Typescript supports files that may include current JavaScript library data, as are header files C ++ Can define the construction of current object files, which allows other programs to exercise the values defined in the files as if they were typical typical entities.
There are third-party header files for prevalent libraries such as D3.JS, JQuery and MONGODB. Typical headers script for node.js elementary modules are also accessible, allowing the development of node.js programs in Typecript.
The TypeScript compiler is written in Typescript and assembled in JavaScript. It is recorded under the Apache 2.0 license.
Advantages of TypeScript
Typescript is an option that remains privileged by developers who want to produce a clean and beautiful, compact and readable code. It is ideal for your large -scale projects or if your team has many developers working on a big project. As such, the Access modifiers and theinterface Typescript can be an additional advantage in the communication of APIs.
If your project uses React And that your team is not used to its API, Typecript offers type definitions. You can also use Intelisense, which will help you navigate and check the new interfaces.
It is not easy to develop simple javascript code, especially if you prefer the verification of errors at the time of compilation: with types Script, it is quite possible to execute a type confirmation at the time of execution, and validation at the time of compilation.
What differences between Typescript and JavaScript?
The TypeScript vs JavaScript combat opposes many categories. Let us pass together in reviews all the differences which distinguish these two languages.
The ecosystem
The Typecript ecosystem is intuitive and powerful. It allows you to statically type various types of idiomatic javascript features such as intersection, types of union and discriminated union.
JavaScript offers the possibility of discovering and code without construction phase.
Data link
Typescript uses concepts such as interfaces and types to define the data used.
No notion of this type is presented in JavaScript.
The learning curve
Typescript has a fairly steep learning curve and requires advanced scripting knowledge.
JavaScript is however easy to learn and constitutes a flexible language for writing scripts.
NPM packages
With typescript, countless NPM packages have definitions of static types (or have an exterior, easier to install).
JavaScript has the ability to search and train code, always without any construction stage.
Annotation and typing
To make the most of these characteristics, standard developers Script must constantly annotate the code, while no annotation is necessary for JavaScript.
The compiler
The TypeScript code must be compiled while there is no obligation to compile the code in JavaScript.
Customer side / Server side
Although it can be used on the server side, Typecript is mainly used on the customer side. JavaScript is also used on the server side as on the customer side.
In fact, although it is presented as a “super javascript”, Typecript is not intended to replace or make JavaScript obsolete. JavaScript resists and always remains the most popular customer side script language.
The community
Typecript has a smaller community of developers than JavaScript, the latter being much more popular with software developers.
Choose between Typescript and JavaScript
By observing the differences between types Script and Javascript, we can say that the two technologies, while being close, have their advantages and disadvantages.
JavaScript is the most suitable when you have a modest team, which works on small web projects. On the other hand, if you have a team with more experience, good knowledge and want to entrust them with the management of a more complex project, then Typecript is a more judicious choice.
For the most modest projects, using TypeScript can represent an overload, because the transcription of the code into JavaScript takes time, which constitutes an additional step for the rendering. JavaScript being executed directly on the browser, it is easier to refresh or debug the code for small scripts, while in the case of Typecript, the developer will need a Ide and an appropriate configuration to execute your code.
